    You might of found the answer the way I did but there is another way and why it's children who would get it.I found the easier way by googling which I think is alright if you already figured the answer(the actual answer not the formulae).

    Re: Another puzzler

    It gave you all the info you need to figure it out. The most important part was that you need no math skills besides basic counting (due to age that can solve it)

    Once you start thinking in that mindset it really should be pretty simple to figure out.

    Re: Another puzzler

    Ah makes more sense what Krischan was talking about,as in counting not basic mathematics.Its actually more logic based than mathematics if you solve it the other way(unless theres yet a 3rd way hidden in it).

    Re: Another puzzler

    HAHAHA!! I looked at that for about 10 minutes last night, and was like "whatev'!" I looked at it again now for just a couple of minutes and figured it out! That's evil!!

    Re: Another puzzler

    So is the answer 2? because i think i found a pattern that works, and its really stupid, but the comments in here make me think I got it.

    and yes, it would not have happened without the hint that kids are better. I was all off checking even / odd, prime numbers, variations of adding and subtracting etc. The 0000=4 line kept thwarting all my theories.

    That's the thing; there's no doubt once you recognize that it has nothing whatsoever to do with the representation of the numbers themselves.

    Re: Another puzzler

    Well, I also got the right answer in about 5 minutes. Then I googled the answer and found that I got to it the wrong way. That said, if it takes a programmer an hour to get it as a straight logic problem they are probably in the wrong line of work.

    Well, pattern recognition is a very useful characteristic in a programmer, but I don't believe it is essential. It's like mathematics; I wasn't a great programmer because I have poor simple math skills, yet my pattern recognition and linguistic skills are top notch.

    Before anyone asks, I cheated per my OP because I was lazy and curious; I didn't really try to solve it. I love "bar puzzles" too...

    Re: Another puzzler

    I think it's more that if it was worded in a more truthful way the clue wouldn't of worked,obviously it didn't work on some of us anyway.

    I think that I like doing logic problems made me do it the way I did but I don't particularly like solving riddles.
